CA3225Y - 225Amp Circuit Breaker

CA3225Y - 225 Amp Circuit Breaker

The CA3225Y molded case circuit breaker is a 225 amp, 3-pole breaker designed for dependable circuit protection in commercial and industrial electrical distribution systems. Built on a CA frame with a non-interchangeable trip unit, this breaker provides consistent overcurrent protection at up to 240VAC with a 10k A.I.C. rating. Designed for operation in environments up to 40°C, the CA3225Y is well suited for maintaining and servicing existing electrical infrastructure where proper form, fit, and function are essential. Line-side lugs are included, helping ensure secure and code-compliant conductor termination. Like many molded case circuit breakers built for demanding applications, this unit is built to last and engineered for long-term service in established systems.

Whether you’re replacing a breaker in a panelboard or servicing distribution equipment, the CA3225Y offers the ratings and configuration required to maintain system integrity while meeting standard overcurrent protection requirements.
